These toppers are specially designed with an extra deep-fill section to provide extra support to the lower back while you sleep. Moulding naturally to your body shape, they give you full-length support even if you sleep on your side or front. Each quality topper is deep-filled to a depth of 10cm giving you extra loft for a sublime night's sleep. Comes complete with elasticated straps to securely fit around your mattress. The Topper has a twin seam box construction to keep its shape and a pure cotton cambric cover for superior comfort and durability.
